Beta patch 13 is now live and we can begin testing the skill/rune changes that Jay Wilson wrote about in his newest blog post. Here are the full notes the Lylirra posted about what the patch did:

A number of significant changes have been made to the character skill and rune systems, as well as to the gold and currency-based auction houses. To learn more about these changes and why they were made, please read the Skill and Rune Changes blog written by Jay Wilson and the Beta Auction House Changes Incoming forum post.

General

All characters have been wiped. Please note that this wipe will also affect gold, achievements, items, followers, and artisans.

Intelligence now grants 0.1 per point to resistances, and will no longer award any bonus to healing from health globes

When dual-wielding, certain skills will now always use your main-hand weapon to determine damage

For example, Cyclone Strike will use your main-hand weapon damage even if your off-hand weapon is set to swing next

An option to permanently enable Advanced Tooltips has been added to the Gameplay Options

Auction House

The gold auction house is once again available for testing

The listing fee for all auctions has been removed

The transaction fee for auctions in the currency-based auction house has been increased to 1.25 Beta Bucks

The minimum listing price for an item in the currency-based auction house has been increased to 1.50 Beta Bucks

Players may now only have 10 active auctions per auction house

Tooltips have been added which will allow players to compare items on the auction house to the items they’re currently wearing

Battle.net

Public chat is now available to test

Cross-game support has been added! You can now chat with Real ID friends playing the World of Warcraft PTR or StarCraft II PTR, as well as view their in-game status.

Skills

The levels at which both active and passive skills unlock have been adjusted for all classes

Skill runes are now available for testing

The first skill rune will unlock for all characters at level 6, and players can unlock additional runes as they level up

In total, players will be able to gain access to 5 skill runes for each skill by level 60

Character skills have been broken down into categories, and each category has been assigned to a specific mouse button or action bar slot in the skill UI

The following categories will be shared by all classes:

Primary Attack

“Primary Attack” applies to skills that typically generate resources and can be used frequently

By default, Primary Attack is assigned to the first mouse button

Secondary Attack

“Secondary Attack” applies to more powerful skills that are commonly limited by a cooldown or resource cost

By default, Secondary Attack is assigned to the second mouse button

Defensive

“Defensive” applies to skills which can be used to escape or control the flow of combat

By default, Defensive is assigned to the first action bar quick slot

Each class will also have three additional categories which are unique. By default, these categories will be assigned to the second, third, and fourth quick slots in the main action bar.

Elective Mode: For players who wish to explore character builds which cannot be accomplished with the provided categories, an “Elective Mode” has been provided. When activated, Elective Mode will allow you to place any skill in any skill category slot, as freely as you could before.

To enable Elective Mode, simply check the corresponding box located in the Gameplay Options menu.

The cooldown on swapping skills has been decreased from 30 seconds to 15 seconds
